I don't know if this will answer your question but one thing is clear in my mind. That it is not for me alone to decide the number of children that I would have. It is between me, my spouse and God. For this reason, I answered "no ideal number" because I want to be open to having the number of children that God wants me and my future spouse to have based on a prayerful discernment of God's will for our family.
Having said that, I am praying to God to 'hurry up' in giving me my future spouse so that I could have the children that he wants me to have. Of course, I am kidding. While I pray and work on it, I leave everything to God's loving providence.
Have a great day!
Children are indeed blessings. I'm open to as many as God will allow me to help set on the right path. In the end, we can SAY how many children we want, but God directs that little detail. :-)
